SolarCalc PH Pro — Solar Design Calculator

Description

Solar Calculator Philippines — Professional Grade, Philippine Specific

SolarCalc PH Pro is a complete solar system design and financial calculator built exclusively for the Philippine market. Unlike generic online tools that only accept your monthly bill and give you a rough panel count, SolarCalc PH Pro performs full engineering-grade calculations following NEC Article 690, IEEE 1562, and PEC 2017 — the same standards required by MERALCO, NORDECO, DLPC, and other Philippine distribution utilities for net metering applications.

Designed for solar installers, registered master electricians, electrical engineers, solar sales agents, and architecture firms across the Philippines, SolarCalc PH Pro is the only downloadable, offline solar calculator built for Philippine conditions, Philippine utilities, and Philippine equipment pricing.

Why Solar Installers and Engineers in the Philippines Choose SolarCalc PH Pro

Every other solar calculator in the Philippines is a free lead-generation tool built by an installer company. They are designed to collect your contact details — not to help you design a system. SolarCalc PH Pro is different. It is a professional tool that you own and use for every project, every client, every quotation.

International tools like HelioScope cost $159 per month (approximately ₱9,000/month) and are designed for the US and European markets. They do not include NORDECO rates, DLPC rates, or Philippine equipment pricing. SolarCalc PH Pro costs ₱999 one time and works forever — including in areas with no internet connection.

Complete Engineering Calculations

SolarCalc PH Pro performs the full set of engineering calculations required for a professional solar system design in the Philippines:

• PV Array Sizing — IEEE 1562 combined method with temperature derating (NEC 690.7), panel degradation, and system efficiency losses
• Battery Sizing — Three modes: Night Only (daily cycling), Night Plus Backup (outage protection), and Extended Autonomy (typhoon preparedness — unique to Philippine conditions)
• String Configuration — Maximum and minimum string voltage calculations at STC, cold temperature, and hot temperature conditions per NEC 690.7(A)(1)
• Inverter Sizing — Continuous rating, surge peak, and MPPT compatibility checks
• Load Audit — NEC 220 demand factors for five load types with VA column for inverter sizing
• Net Metering — ERC-compliant bill credit model for all six Philippine utilities
• Financial Analysis — 25-year NPV and IRR with panel degradation, rate escalation, and bank financing comparison

All Major Philippine Utility Rates Included

SolarCalc PH Pro is the only solar calculator that includes rates for all major Philippine distribution utilities — including NORDECO, the utility serving Tagum City and Davao del Norte, which has the highest residential rate in the Davao Region at ₱12.90/kWh as of 2025. This makes SolarCalc PH Pro especially valuable for solar installers and homeowners in Tagum, Panabo, Carmen, Santo Tomas, and the broader Davao del Norte service area.

Utilities included: NORDECO (Tagum/Davao del Norte), DLPC (Davao City), Meralco (Metro Manila and Luzon), VECO (Cebu), BENECO (Baguio and Benguet), BOHECO (Bohol), and a custom rate input for any other distribution utility.

Philippine Equipment Database — 2025 Trade Pricing

The built-in equipment database contains 90 plus items with 2025 Philippine distributor trade pricing. Panels from Jinko Solar, Longi Solar, Canadian Solar, Trina Solar, JA Solar, and local brands. Inverters from Growatt, Deye, SolaX, Solis, Huawei, Sungrow, GoodWe, and more. Batteries from Pylontech, BYD, Growatt ARK, and Victron. All equipment is single-phase residential grade — the most common installation type in the Philippine market.

Professional Client Quotation and Business Tools

SolarCalc PH Pro includes a full set of business tools designed for solar installers who need to present professional proposals to clients. The Client Quotation generator produces a clean, print-ready quotation document with your project details, system specifications, and itemized costs. The Markup Pricing tool lets you set profit margins per line item so your client sees your selling price — never your cost. Export to CSV for import into any CRM or accounting system.
